Lost Power and Died

While driving on the highway my truck suddenly lost power came to a stop then the engine died. I had previously had the truck in the dealership for engine problems. Rough idle, jerking. They diagnosed P1280. PID monitored ICPV 0 volts, wiggle tested harness went to .19V. Needs sensor and pigtail replaced.

I was unable to afford what they charge for the repair so i found the parts online. I never installed them bc the truck ran fine and didn't act up one time since they checked it, until today.

When the engine died it would not run. Would crank and want to fire but very rough and would not run. I got P0733 and P1211 codes. I changed the ICP sensor and the truck would then start and remain running although very rough. Also, would not move, had no power at all. After this I got P1280 repeatedly as the only code. I replaced the pigtail harness. Still getting P1280 code with still very rough idle. Truck will now move although with almost no power and only like 1 mph.

Any ideas are appreciated. I cant afford to take it to the dealership.

I don't know what those codes are and I'm not anywhere I can look them up but I have a few ides.

1. unplug the icp and see if it starts. if so icp bad

2. can the scanner you are using read high pressure oil pressure? IF so what is it. You need at least 500psi for the engine to start. If the scanner can't read hpop psi then you can make your own gauge. I don't know the sizes of the fittings. Ask people on here know. They are standard sizes so getting some is easy. Read from the outlet of the hpop and take out the icp and read there too.

3. what is the battery voltage while cranking? You have to have 10.5v before the pcm will open the injectors.
Hope this helps.

Is that really true? I thought if it was unplugged the computer would default to an assumed +/-500psi to fire the injectors.
